Key features

• •4000W Pure sine Wave Inverter is a new all-in-one hybrid solar inverter charger, Tempered glass top cover design + touch function, one key to restore the default settings. The default mode is Off Grid. You can manually enable On Grid.
• •4KW Hybrid Solar Inverter Max.PV Input Power: 5600W, Voltage range: 55-350Vdc, Max. PV Input VOC: 350V DC, Starting voltage >90V;The best working voltage is 55-280V;Max. charge current: 140A. Nominal Input Frequency: 50/60Hz;Output Power: 4000W, surge Capacity: 8000w. fit for 24V Lead-Acid (Seal, AGM,Gel, Flooded) and Lithium battery
• •Off Grid Solar Inverter have 4 charging modes are optional, i.e. Only Solar, Mains Frist , Solar Frist and Mains & Solar hybrid charging;and 3 output modes are available, i.e. Solar Frist, Mains Frist and SBU Priority, uninterrupted power supply to meet different application requirements. And compatible to mains voltage or generator power, Auto restart while AC is recovering.
• •Built-in BMS function.Lithium Battery Activation， has a reactivation feature to awaken a sleeping lithium battery. Inverter work easy to heat, traditional design of 2 cooling fans, Y&H design of 3 fans, better cooling function, improve work efficiency, prolong the life of the inverter.
• •Battery-less startup design significantly reduces system purchase cost. Battery installation, maintenance and replacement costs are eliminated. Direct utilization of photovoltaic power, suitable for daytime high energy consumption scenarios, especially in areas where solar energy resources are abundant and demand for electricity is concentrated in the daytime (it is recommended to match the grid input, which automatically switches to utility power to supplement when there is insufficient photovoltaic power generation)
